Answer:
Option B
Explanation:
Gravitational force is a force that attracts two bodies (with a mass) towards each other. If an object has a higher mass, the gravitational pull will be greater.
According to Newton’s inverse square law: 
<em>"The gravitational force is inversely proportional to the square of the distance between two bodies."</em>
About this question, the greater the distance between two gravitating bodies, the weaker is the gravitational force between them.
 
        
             
        
        
        
Previous rocks melt and collide and to form igneous rocks.
Igneous rocks disintegrate due to weather disruptions and get carried away by water, where they form sedimentary rock strata by lithification.
Igneous and sedimentary change by heat and pressure to form metamorphic rocks.
Metamorphic rocks melt and become igneous rocks.

Answer:
a
   
b
   
Explanation:
From the question we are told that 
           The mass of the rock is  
           The  length of the small object from the rock is  
           The  length of the small object from the branch 
An image representing this lever set-up is shown on the first uploaded image 
Here the small object acts as a fulcrum 
The  force exerted by the weight of the rock is mathematically evaluated as
       
substituting values 
      
      
  So  at  equilibrium the sum  of the moment about the fulcrum is mathematically represented as 
          
Here   is very small so
 is very small so   
 
                                and  
Hence 
        
=>    
substituting values 
         
        
The  mechanical advantage is mathematically evaluated as 
           
substituting values 
         
        
 
        
             
        
        
        
When you talk about Hooke's law, it always have to do something with springs. Hooke's Law, from Robert Hooke, saw a relation between the force applied to the spring and the extension of its length. The equation is: F = kx, where k is the spring constant and x is the displacement of the original and stretched lengths. In other words, x is the length of deformation. Hence, the object must be elastic to come up with a displacement or deformation, in the first place. Then, the Hooke's Law is only applicable to elastic materials.
